In this video I’m just showing one way of getting 120v AC out of a car alternator with low rpm engine to generator setup. DO not try this at home this is just for entertainment purposes. The wiring of the transformers and diagrams is not exactly correct you must wire them so they are in phase with each other, the transformers have a specific way you must wire them together. I could not show this because I am using homemade transformers on my working generator. You may not have to use transformers to get 120v out of an alternator if you spun it at high rpm by using a large pulley on the engine but i am showing this a a lower rpm.
